Introduction • Tandemly repeated DNA sequences are widespread throughout the human genome. • These tandemly repeated regions of DNA are typically classified into several groups depending on the size of the repeat region. • Minisatellites (Variable Number of Tandem Repeats, VNTRs) have core repeats with 9- 80 bp • Microsatellites (Short Tandem Repeats, STRs) contain 2-5 bp • repeat varieties (dinucleotide repeats:CA, AT, TC, trinucleotide repeats: TTA, tetranucleotides, pentnucleotides, etc.).
